Embodiment Construction

[0010] refer to figure 1 1. Install a heated push mechanism and a push-pull electromagnet on the cavity 12, and the magnet push rod 3 of the push-pull electromagnet is fixedly connected with the push rod 5 of the heated push mechanism. The push-pull electromagnet consists of a coil 2, a magnet push rod 3 and a plug 1. The coil 2 is installed in a round hole provided on the cavity 12. One end of the magnet push rod 3 is inserted into the inner hole of the coil 2, and the other end of the magnet push rod 3 Extending into the cavity 12, a sealing ring 4 is provided at the joint between the outer circumference of the magnet push rod 3 and the cavity 12, the plug 1 is fixed on the cavity 12 and pressed on the coil 2, the wire end of the coil 2 is electrically connected to the plug 1 connect. The heated pushing mechanism includes a push rod 5, a gland 6, an apron 7, a body 8, a valve 9, paraffin wax 10, and a spring 11. A push rod 5 is inserted in the inner hole of the body 8 with ...

Abstract

The invention adopts a double-control thermosistor. A heating pushing mechanism provided with a valve and a push rod is mounted in a cavity; a push-and-pull electromagnet is arranged on the cavity; and a magnet push rod of the push-and-pull electromagnet is fixedly connected with a push rod of the heating pushing mechanism. According to the invention, the double-control temperature adjustment is realized through additionally arranging an electrical control driving control device based on the fact that the traditional paraffin type thermosistor and other thermosistors operate depending on heating of coolant liquid of engines, solves the problem that the electrical control thermosistor is incapable of normal operation in case of current failure, and solves the defect that the thermosistor controlled through the heating manner of the coolant liquid cannot be correspondingly adjusted along with change of working condition or external environment; and the matching of two adjustment and control manners improves the controllability and reliability.

Description

technical field [0001] The invention relates to a thermostat used for water cooling control of an internal combustion engine, in particular to a dual-control thermostat. Background technique [0002] Similar products currently on the market include wax-type thermostats and electronic thermostats. Thermostats are also called thermostats. (1) The wax-type thermostat works by feeling the temperature of the coolant in the cooling circuit through the paraffin inside the thermostat. When the temperature of the coolant in the cooling circuit rises to the melting temperature of the paraffin, the paraffin melts, expands in volume, and generates an expansion force, which is transmitted to the push rod and converted into the thrust of the push rod to realize the opening of the thermostat. When the coolant temperature When it is lowered, the paraffin shrinks due to cold, the expansion force disappears, and the thrust of the push rod disappears accordingly, and the thermostat is closed ...
